It stays searchable; available government estimates remain below (data tier: Profile).

Each point is one ACS 5-year estimate on the same 2020-Census ZCTA boundary. Adjacent releases overlap, so the release-to-release differences are not independent annual market movement.

Missing releases remain gaps and are never interpolated. Home value is owner-reported; gross rent describes renter housing stock; population is a ZCTA estimate. Dollar figures are nominal.
Measured market data
Measured observations for this ZIP Code, published beside the government survey figures above rather than replacing them. They measure different things and will legitimately disagree; the reconciliation below states on which axis, one axis at a time, instead of leaving a reader to guess. ZORI does not correct the ACS rent; neither is a better version of the other. Monthly series, revised in recent months, observed 2026-08, not live.

Zillow keys on USPS ZIP codes; this page is a 2020 Census ZCTA, related but not identical geographies, so a Zillow value is matched to this ZCTA by code and is not a statement that the two areas are the same.

Underwrite with these as starting points
Opening a calculator pre-loads the ACS median owner value as a survey-level starting point; every calculator input is editable. Owner-occupied median value and renter median gross rent describe different housing stock: the median-valued home is not the typical rental, so this is a screen, not a listing, appraisal, asking rent, cap rate, or forecast. Bring your own entry price and rent.
ZIP Codes bordering 04359
1 ZIP Code area shares a land boundary with 04359 in the official Census 2020 ZCTA map, ordered by shared-boundary length, not ZIP-number proximity or driving distance. 1 of them is in CE’s ranked set and is listed below, each with its own Rental Investor ZIP Score, grade and national rank, read from the same published dataset as this page. The rest are counted here and searchable from the ZIP Code explorer. A neighbour’s score is a score for that area, never for 04359, and this list is ordered by border length, so it is not a ranking and no neighbour is called best.

Class: survey = ACS estimate (with margin of error); derived = computed from ACS. The survey gross-rent yield is a proxy (renter gross rent vs owner-occupied value, different housing stock; ACS top-codes very high values/rents) and is not a cap rate. Subscores are national percentiles among data-eligible areas; ranks are competition-ranked with deterministic ties. No vendor, listing, parcel, or school data. Not investment advice.
